90Sr decays with the emission of a 2.8 MeV beta particle. Strontium is chemically similar to calcium and is taken up by bone. A 75 kg person exposed to waste from a nuclear accident absorbs 90Sr with an activity of 370,000 Bq. Assume that all of this 90Sr ends up in the skeleton. The skeleton forms 17% of the person’s body mass. If 50% of the decay energy is absorbed by the skeleton, what dose equivalent in Sv will be received by the person’s skeleton in the first month?
